Can You Compare Spray Foam Insulation to Foam Board?

When you’re trying to decide between the many different insulation types available, you may happen upon foam board insulation and decide you have it made. It is, after all, a great insulation product that can help create an air seal, when installed properly. If you compare spray foam insulation to foam board insulation, however, the choice becomes a clear one.

The primary benefit of spray foam insulation like Icynene over rigid foam board insulation like XPS foam board is the difference between having parts of your building with an effective air seal and all of your building effectively air sealed. This is due to the fact that Icynene spray foam can be applied in small, out of reach parts of your home’s building envelope. This, along with Icynene’s ability to expand rapidly within seconds of application to fill every cavity and crevice, can make it more effective at creating a complete air barrier for your home, helping to minimize drafts and air loss.

If your building has any architectural features that might present a challenge for pre-made insulation like foam board or batt insulation, then Icynene spray foam may be exactly what you’ve been looking for.
